Modélisation de la Structure Complexe des Faits et des Mesures

Decision support system (DSS) goal is to help decision-makers. They are modeled mainly in a multdimiensional way, that means activity analysis subjects, called facts, with their measures are represented as the center of a star with dimensions and their parameters around. Several models have been devoted to DSS representation, but they handle only relationships between dimensions and their param...

Autour de nouvelles notions pour l'analyse des algorithmes d'approximation : de la structure de NPO à la structure des instances

This paper is the continuation of the paper “Autour de nouvelles notions pour l’analyse des algorithmes d’approximation: Formalisme unifié et classes d’approximation” where a new formalism for polynomial approximation and its basic tools allowing an “absolute” (individual) evaluation the approximability properties of NPhard problems have been presented and discussed. In order to be used for exh...

A Characterization of Hyperbolic Kato Surfaces

We give a characterization of hyperbolic Kato surfaces in terms of the existence of an automorphic Green function on a cyclic covering. This is achieved by analysing a naturally defined Levi-flat foliation, and by perturbing certain Levi-flat leaves to strictly pseudoconvex hypersurfaces. 2010 Mathematics Subject Classification: Kato surfaces, Levi-flat foliations, plurisubharmonic functions.

Manipulation de contenu 3D sur des surfaces tactiles

Since the emergence of tactile surfaces in recent years, the general public uses them every day for multiple tasks, such as checking email, photo manipulation, and so on. However, very few 3D applications on these devices exist, although such applications may have great potential in various elds, such as culture, architecture, or archeology. The major di culty for such applications is to intera...
